Answer:

The correct choices are: Both tables are relations because both display a set of ordered pairs, and table B is a function because each input has exactly one output.

Step-by-step explanation:

Both statements are true, both tables can be considered relations since all functions are relations, and because table A has proper inputs and outputs despite the fact of the same inputs resulting in different outputs. Table B can be considered a function because it has different inputs that each have an output, and there is no same input value that results in different outputs.

Answer: x(8) - /81

Step-by-step explanation:

Answer:

Step-by-step explanation:

As before any expression of the form (a^2-b^2) will always factor to (a-b)(a+b) in this case

x^8-1/81 = (x^4-1/9)(x^4+1/9) = (x^2-1/3)(x^2+1/3)(x^4+1/9) and if we completely factor it including square roots.[tex](x-\sqrt{1/3})(x+\sqrt{1/3})(x^2+1/3)(x^4+1/9)[/tex]

Answer:

1) 14

2) m<1=47°

3) m<2=47°

Step-by-step explanation:

1) 75-2x=89-3x

-2x+3x=89-75

x=14

2) m<1=75-2x

75-2(14)

75-28

47

3) m<2=89-3x

89-3(14)

89-42

47

Answer:

The pair of numbers is (3,3) while the maximum product is 9

Step-by-step explanation:

The pairs of numbers whose sum is 6 starting from zero is ;

0,6

1,5

2,4

3,3

Kindly note 2,4 is same as 4,2 , so there is no need for repetition

So the maximum product is 3 * 3 = 9 and the pair is 3,3

Answer:

Linear

Step-by-step explanation:

The equation is in y intercept form.

Answer:

Step-by-step explanation:

Part A:

Rate of pay for David = [tex]\frac{\text{Change in earnings}}{\text{Change in hours worked}}[/tex]

                                            = [tex]\frac{3700-3200}{140-120}[/tex]

                                            = $25

Part B:

If he worked for number of hours = x

Then the function representing the earning will be,

f(x) = 25x + b

For an ordered pair (120, 3200),

3200 = 25(120) + b

b = 3200 - 3000

b = 200

Therefore, function will be,

f(x) = 25x + 200

Part C:

"Slope = 25" means the rate of change in earnings per hour is $25.

Similarly, y-intercept 'b = 200' will represent the fixed amount earned by David in addition to the per hour earnings.

Answer:

142.5 gallons

Step-by-step explanation:

Divide 570 by 4 and then use that for one side

Answer:

6°

Step-by-step explanation:

8m + 4° + 38° = 90°{ being complementary angles}

8m + 42° = 90°

8m = 90° - 42°

8m = 48°

m = 48° /8

m = 6°

Hope it will help :)

Answer:

4.1 shirts

Step-by-step explanation:

Mean can be found by adding all data points and dividing that by the total amount of data points.

There are 12 students selling shirt, which gives you 12 data points.

So (3+4+8+5+2+5+0+5+3+4+3+7)/12 = 4.083...

Which rounds to 4.1 shirts

Answer:

The correct answer is C: 4.1 shirts

Step-by-step explanation:

Answer:

Movie Rental B is better to buy. It's cheaper by .75 cents.

Step-by-step explanation:

Solving Movie Rental A

To find the unit rate of this one, we divide the dollars and the rentals.

So, 15 ÷ 3 = 5

Unit Rate for Movie Rental A is 5

Solving Movie Rental B

Same as Movie Rental A, divide the dollars and the Rentals.

8.5 ÷ 2 = 4.25

The number with the less amount is cheaper so

4.25 is less than 5

Answer:

26

Step-by-step explanation:

first, substitute the value for x into the expression. since x = 6, you will be plugging in 6 for x.

4x + 2 ⇒ 4(6) + 2

simplify the expression, starting with 4 · 6.

4(6) + 2 ⇒ 24 + 2

then add 24 + 2.

24 + 2 ⇒ 26

aaaand your answer is 26! hope this helps. have a lovely day! <3

Answer:

9). 15 miles

10). 12880.8 in²

Step-by-step explanation:

9). Total distance to be covered by Kelly = Perimeter of the given triangle

                                                                    = Sum of three sides of the triangle

    To know the length of Laurel drive (Hypotenuse of the triangle), we will apply Pythagoras theorem in the given triangle,

    (Hypotenuse)² = (Leg 1)² + (Leg 2)²

                             = (2.5)²+ 6²

                             = 6.25 + 36

     Hypotenuse = [tex]\sqrt{42.25}[/tex]

                           = 6.5 mi.

     Therefore, total distance covered by Kelly = 6.5 + 2.5 + 6

                                                                             = 15 mi.

10). Amount of paper required to cover one desk of the class

     = Area of the trapezoid shown in the figure

     = [tex]\frac{1}{2}(b_1+b_2)h[/tex]

      Here, [tex]b_1[/tex] and [tex]b_2[/tex] are the parallel sides of the trapezoid

      And 'h' is the distance between the parallel sides.

      By applying Pythagoras theorem in ΔPRT,

      PR² = RT² + PT²

      PT = [tex]\sqrt{PR^2-RT^2}[/tex]

      PT = [tex]\sqrt{(18)^2-2^2}[/tex]

            = [tex]\sqrt{324-4}[/tex]

            = [tex]\sqrt{320}[/tex]

            = 17.89 in.

      Area of the trapezoid PQRS = [tex]\frac{1}{2}(PQ+RS)(PT)[/tex]

                                                      = [tex]\frac{1}{2}(22+26)(17.89)[/tex]

                                                      = 429.36 in²

      Therefore, paper required to cover 30 desks = 30 × 429.36

                                                                                   = 12880.8 in²

Answer:

161

Step-by-step explanation:

69 is 30% of 230 so 230-69=161 is the answer.

Answer:

x=136 degrees

Step-by-step explanation:

ok so basically the angles are the same because the line intersects both lines at the same degree.

Answer:

136°

Step-by-step explanation:

Since both line are equal in length and size and both straight then if on side is 136° then the other side must be 136°
